ROTARY ENGINE.

To all whom it may concern:

Be it known that we, TOSSANUS DUYSENS, JoHAN REeINns HENRI DE JONG, andHEN- DRICUS LUnovIcUs KNnrrnRs, citizens of the Kingdom of theNetherlands, residing in Maastricht, Netherlands, have invented a newRotary Engine, of which the following is a complete specification,reference being had to the accompanying drawings.

The present invention pertains to rotary engines calculated for rightand left driving or for one-sided driving and provided with variable andadjustable expansion.

The present invention is of such a nature that the paddle protrudingfrom a piston body durlng the revolution thereof is made use of, withthe projections of the exit parts of the working piston in such a mannerthat these projections are also utilized as paddles. By this means theutilization of the steam efficiency is rendered more complete, becausesimultaneously or alternately the steam pressure can be directed againstthe projection paddles or against the piston paddles, or against bothtogether, with uniform expansion effect of the steam passing out betweenthe projections or of that against the piston paddles. This arrangementhas the special advantages that there can be a change made alwaysmomentarily from the minimum up to the maximum inherent efficiency ofthe rotary engine, a property which in many branches of industry is verydesirable. The rotary engine thus operates like an electromotor. Jerksin the moving parts which are liable to cause breakages are renderedimpossible, because the rotary engine owing to the arrangement of thesteam inlet will only give out the power which is required of it at themoment. It can also work immediately with steam of opposite direction.

The accompanying drawings illustrate the improved rotary engine.

Fig. 3 shows a transverse section with the springs omitted.Fig. L is a longitudinal section on an enlarged scale. Figs. 5 and (3show details relating Specification of Letters Patent.

to the outer casing and the control mechamsm.

\Vithin the casing a (Figs. 1, 2, 3 and 4.) there is placed upon theaxis 0 the disks .7) closing the said casing and the revoluble piston c.The disks 6 render, by means of their surfaces of contact, the interiorof the casing completely steamtight. The revoluble piston is providedinside the slides e and at its periphery with the steam plates 7 whichoccupy with the openings lying between them, an entire segment of theperiphcry of the driving piston. Between two of these segments arearranged the wings g which are placed in such a form in the pis ton uponrods h that the opposite ones always rest against the inner peripheralsurface of the casing. In order more perfectly to achieve this purpose,there are placed upon the ends of the wings or paddles 9 socalled shoes2' which, owing to their curved outer surface, apply themselvesaccording to the direction of revolution of the piston against theperiphery and thereby secure a reliable steam-tightness. In orderhowever, to assure a similar tightness of the driving piston c or of thepaddles 9 against the inner periphery of the casing, at the place wherethe plates 7 come into play as paddles for the steam pressure in frontof the openings of the steam inlet channels la, Z there is provided thecasing arch 3 .2 (Fig. 5) fitted to the diameter of the driving piston cor of the paddles against the inner periphery of the casing while forthe development of the expansive force of the steam in continuousrevolution of the piston or of the greater protrusion of the paddles gthe side parts 10, m (Fig. 5) of the inside of the casing are formed upto their undermost unction, which takes place at the pivot '11, ofeccentric shape. The steam outlet at is also placed atthe point e (Figs.1, 2, 3, By this construction of the inner casing space there is securedon the one hand to keep steamtight the piston periphery of one segmentof blades over against the steam inlet opening and on the other handcorresponding to the expansion of the entering steam to offer thenecessary pressure surface to the paddles proceeding out of the body ofthe piston; in this constructio-n the distance between the opposedpaddles and the points of the inner casing Wall which come in contactwith them remain the same. Such steam inlet channels are provided forthe right and the left revolution of the rotary engine to the extent offour namely is, Z, n, p (Figs. 1 and For one side turnin only two, forinstance g, r are necessary Fig. 2). lVith the first of these 70, Zserve for the segment plates f if they are under the channels evenwithout reference to the respective slides e and when the plates thenserve as paddles. If the plates proceed farther, then the slide 6effects the closing of certain channels which lie between the plates andadmits of the introduction of an expansion system. In the one sidedmachines (Fig. 2) the channel 9 serves for this purpose.

The outer steam conducting channels a, 79 (Figs. 1 and 4t) and r (Fig.2) also conduct the steam to the plates and paddles. The disposition ofthe steam inlet channels .70, Z, n, 2) (Figs. 1 and 4) and g r (Fig. 2)is necessary for the utilization of the smallest and the greatest powerefiiciency of the machine, because it can occur that suddenly thetransfer from the smallest to the greatest power becomes necessary andvice versa, as for instance in ships, in rolling mills and so forth. Insuch cases the rotary engine works with full efliciency in itsrespective rotation from the respective channels 70, n or Z, p (Figs. 1and 1) or q, a" (Fig. 2). If a diminished power is required, then theinlet channel a or p or 1" can be closed and the channel 70 or Z or Qthen supplies the working steam between the plates 7 against the paddleg. The rotary engine consequently works with full pressure, withadjustable expansion, or with full pressure and fixed expansion,according to the amount of power which is required from it.

It is obvious that through the arrangement of the steam inlet channelsplaced on both sides 76, n, Z, 7) (Figs. 1, 2) a right or leftrevolution of the driving piston 0 is assured together with a minimumand maximum power effect. Each can be immediately adjusted as theadmission of the steam is regulated by means of the :cock t placed onthe pipe .9. The channels on the other side lying opposite the turningside are of course then closed. Further it is obvious that in the caseof the one-sided rotary engine, such for instance as that shown in Fig.2, a right sided operation can be effected in the same manner. The axis0 is supported outside of the casing a revolubly in the bearings a. Itcarries a pulley 1 (Figs. 3 and 6) which by means of the screw 2 can bemoved to and fro. It serves for the adjustment of the automaticallyacting expansion. For this purpose between the part 1 and the rings 3arms are inserted movable in the blocks 5, so that on their displacementof the rings 3 these blocks move farther from the center of the axis andon the return they approach it again. To these little blocks 5 areconnected by means of spring 6 on both sides the weighted levers 7, sothat these latter are always kept by the blocks 5 in a certain tension.If the rotary engine is at work, then the revolving slides c possess byreason of their weighted lever ends 7 the tendency to move in thedirection of the centrifugal force, while the springs opposed to therotation tend to restrict this to a limited degree, the amount of whichhowever, is dependent upon the forward or backward displacement of thedisk 1. The turning of the slides e, (l, 2' and the alteration of theexpansion consequently are effected automatically.
